SPINNING MACHINE.

T o all whom it may concern Be it' known that we, EDWARD AUSTIN VATSON and RoLLY J. FLOYD, citizensl of the United States, residing,` respectively, at Anderson and Greenville, in the counties of Anderson and Greenville and yState of South Carolina, have invented certain new and useful Improvements in Spinning Machines, of which the following is a specilication.

The present invention. relates to mechanism for operating` the builder beams of spinning machines that Acontrol the ring .ra-ils, and this is in the nature of a 'modication of the structure disclosed in the patent to Edward Austin Watson, No. 1,350,905,

dated August 24, 1920'. n

The object of the4 present case is to provide an apparatus which may be in the form of an attachment that can be utilized on '20a well-known Jform of beam, and will effectively control the short-stroke mecha nism for said beam.

In the accompanying drawings p Figure l is a View in elevation of a builder beam and cams showing the improved mechanism in place.

Figure 2 is a cross sectional view.

Figure 3 is* a view similar to Figure 2, but illustra-ting the arrangement of the parts during the return of the plunger to its active position.

In the structure shown, the builder beam is designated 4 and the usual. builder cam that operates thereon, is shown at 5. Se

cured to the cam 5 is a short-stroke cam 6, the two cams being mounted on a shaft 7. A bracket 8, fastened by a bolt 9, or other device, to the beam 4, has slidably mountedl therein a transversely disposed plunger 10 provided with a roller 11 that is ada ted to engage and disenoaofe the shortb 25 D D stroke cam 6. The outward movement of the plunger is limited by a stop pin 12 carried thereby and adapted to engage the bracket 8. Y

Fixed to the shaft is 'a worm 13 that is thus rotatable with the cams 5 and 6, and adjustably mounted on the plunger 10 by means of a collar 14 and set screw 15, is an upstanding inger 17 having a terminal blade 18 adapted to engage with said worm. The outer end of the plunger is beveled as shown at 19, and located below and in the path of said beveled end when the plunger 1821. Serial No. 479,351.

is withdrawn, is a liXed cam 20 adjustably mounted in a supporting standard 21,

The operation of the device is as follows: lvyhen the roller 11 is engaged with the cam, shown in Figure 2, the blade 18 will be engaged with the worm 13 and the depth of this worm is sui'fliciently great to maintain sai` engagement within the ment or the. builder beam 4. Consequently it will be evident that as the cams rotate and the beam swings the plunger 10 will be 11 is disengaged from the cam 6. The short stroke mechanism then becomes inactive and the cam 5 operates on the beam 4. When, however, the. beam 4 is abnormally depressed the outer 'beveled end 19 of the plunger will strike the cam 20, and said cam will cause a retrograde movement of the plunger, bringing the roller 11 beneath the cameand in a position to engage the same when the beam rises.

From the foregoing, it is thought that thel construction, operation and many ad' vantages of the herein described invention will be apparent to those skilled in the art,

-without further description, and it will be understood that various changes in the sizes, shapes, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described our invention, what we. claim as new, and desire to secure by Letters Patent, is

1. ln apparatus of the character set l'orth, the combination with a builder beam and a cam for operating it, of a reciprocatory device mounted on the beam and movable into and out of engagement with the cam, and co-aXial means rotating with the cam and directly engaging the device to move it out ci engagement with the cam.

2. ln apparatus of the character set forth,

the combination with a builder beam and a cam lior operating it, of a device mounted on the beam and movable into and out ot engagement with the cam, a co-axial worm rotating with the cam, and an element connected to the devine and engaged with the worm vto withdraw said device from the cam.

3. ln apparatus of the character set forth,

the combination with a builder beam and a gradually withdrawn until the roller limits of movecam for operating it, of a plunger slidably mounted on the beam and `having a portion movable into and out of engagement With the cam, a co-a-xial Worm rotating With the cam, and an element connected to the plunger and engaged With the Worm to Withdraw said plunger from the cam.

4. ln apparatus of the character set forth,

" from the cam.

5. Inapparatus of the character set forth,

' the .combination with a builder beam and a cam for operating'it, oi' a device mounted on the beam and movable into and out of engagementwith the cam, a `Worm rotating With the cam, an element connected to the device and engaged with the Worm to Withdraw said device from the cam, and

means 'for automatically returning the device after its disengagement, When the beam is abnormally depressed.

6. In apparatus of the character'set forth,

the combination lwith a builder beamfand a cam for operatingit, of a plunger slidably mounted on the beam and having a portion movable into and out of engagement With the cam, a Worm rotating With the cam, yan element connected to the plunger and en* gaged with 'the Worm to Withdraw said plunger from the cam, [and a fixed cam in" the path of the'plunger When the beam is abnormally depressed toreturn the plunger.l i
